This package contains the NVIDIA IDE 553 Drivers for parallel ATA (PATA) and 
serial ATA (SATA) drives, and the RAID driver for SATA drives, to support the 
mass storage controllers in the listed workstation models with the NVIDIA 
nForce Chipset and the listed operating system.

NOTE: HP xw9300 Workstations having system BIOS version 2.00 (or later), must 
be upgraded to NVIDIA IDE driver 553 (or later). 

CAUTION: Optical storage devices are the only PATA peripherals supported on the 
HP xw9300 Workstation. The HP xw9300 workstation does NOT support PATA hard 
disk drives in any RAID or non-RAID configuration. If PATA RAID is currently 
being used on the HP xw9300 Workstation, do NOT upgrade to system BIOS 2.00 (or 
later) because of potentially serious side effects. For example, the PATA RAID 
drive may become unbootable, resulting in loss of data.
